Xinrui Laboratory Ultrapure Water Purifier
[Product Introduction]
Xinrui Ultrapure Water Purifiers use tap water as the source and integrate technologies such as microfiltration, activated carbon adsorption, reverse osmosis, ion exchange, UV oxidation, and ultrafiltration to remove impurities like ions, pyrogens, organic matter, particles, microorganisms, and bacteria. This produces pure water that meets the purity requirements for experiments, making it suitable for universities, research institutes, industrial systems, and the medical industry.

Performance Features of RUPF Series Ultrapure Water Purifiers
· Automatic backwashing function upon startup
· Low-pressure alarm shutdown protection; automatic water production stop when the tank is full
· Simultaneous online monitoring of two water quality channels, real-time monitoring of pure and ultrapure water quality
· No-water alarm, full-water alarm for safety assurance
· Fully automatic RO membrane anti-scaling flushing program, extending RO membrane lifespan; automatic backwashing at startup and automatic flushing during standby when the tank is full
· Graded water output, dual-purpose machine (capable of drawing two types of pure water simultaneously)
· Multiple specifications of water storage tanks available to meet different needs
· Ergonomically designed chassis, compliant with GLP standards
· All pipelines are NSF certified; new quick-connect fittings make filter column replacement and maintenance more convenient
· Original imported nuclear-grade resin, fully descending flow ultrapurification column design, ensuring top-tier water quality at all times
· Online monitoring of water temperature in the system
· Dual-wavelength (185nm&254nm) imported UV lamp, effectively sterilizing, reducing TOC, and expanding system applicability
· Original imported 0.45μm PES polyethersulfone composite membrane terminal sterilization filter, ensuring sterile water quality
· Ultrapure water constant pressure system
· Enhanced pretreatment with automatic startup after water use
